Nuclear imagers are using alternatives to keep their practices alive until the National Research Universal Reactor at Chalk River, ON, resumes production of Mo-99
Nuclear imagers are using alternatives to keep their practices alive until the National Research Universal Reactor at Chalk River, ON, resumes production of Mo-99. The shutdown has disrupted 60% of radiopharmacies in the U.S., according to an online survey jointly sponsored by the SNM and the National Association of Nuclear Pharmacies.
Only a third of respondents said they have an alternate source of Mo-99/Tc-99m generators, namely manufacturers with access to isotopes produced in reactors outside of North America. About 84% have eluted older generators more often to draw off as much technetium isotope as possible; 82% are using thallium-201 for cardiac imaging; 6% are performing F-18 FDG-PET bone imaging; and about 9% have shifted to F-18 sodium fluoride (NaF). Indium-111 (5%), gallium-67 (2%), and nitrogen-14 ammonia (1%) were also cited as alternatives.
Can Polyenergetic Reconstruction Help Resolve Streak Artifacts in Photon Counting CT?
July 22nd 2024New research looking at photon-counting computed tomography (PCCT) demonstrated significantly reduced variation and tracheal air density attenuation with polyenergetic reconstruction in contrast to monoenergetic reconstruction on chest CT.
Systematic Review: PET/MRI May be More Advantageous than PET/CT in Cancer Imaging
July 18th 2024While PET/MRI and PET/CT had comparable sensitivity for patient-level regional nodal metastases and lesion-level recurrence, the authors of a systematic review noted that PET/MRI had significantly higher accuracy in breast cancer and colorectal cancer staging.
The Reading Room: Racial and Ethnic Minorities, Cancer Screenings, and COVID-19
November 3rd 2020In this podcast episode, Dr. Shalom Kalnicki, from Montefiore and Albert Einstein College of Medicine, discusses the disparities minority patients face with cancer screenings and what can be done to increase access during the pandemic.
